The curfew, clamped in the arson-hit town on Saturday, would continue till Monday, while the prohibitory orders were imposed in nearby Dhamnagar and Basudevpur as a precautionary measure to prevent spread of violence, a police official said.
Additional forces, including armed police, were deployed as part of an effort to restore peace in the strife-torn town which witnessed violence on Thursday and Friday, he said.
Senior officials, including Home Secretary Asit Tripathy and Director-General of Police K B Singh, have been camping in Bhadrak to monitor and supervise the peace operation.

Stating that he had a word with Union Home Minister Rajnath Singh and the Home secretary on the issue, Pradhan urged Odisha Chief Minister Naveen Patnaik to handle the situation in a sensitive manner and activate the administration.
About 30 people have been detained in connection with the violent incidents which left several shops gutted and vehicles damaged.
All entry and exit points of the town have been sealed, police said.
